Ideologische Grundlagen I: Marxismus,In this chapter we will discuss a series of simple reactions in QED. To begin with we will take electron-electron scattering and will derive the Feynman rules given in Appendix B from the general expression for the S-operator (9.14).

https://doi.org/10.1007/978-3-658-04507-4The muon was discovered in cosmic rays in 1937 (Anderson 1937,1938; Street 1937). It behaves in essentially the same way as the electron, but its mass is about 200 times larger:

Linux System Administration for the 2020sA large part of our knowledge about hadrons stems from various scattering experiments of types differing according to the projectile used. We can study lepton-hadron, photon-hadron, or hadron-hadron scattering.

The Dirac Equation and the Dirac FieldIn Chap. 3 we discussed the theory of neutral mesons. Two elementary particles that frequently occur in Nature, the electron and the proton, are however particles which possess intrinsic angular momentum: spin = 1/2. Since a scalar field offers no opportunity for describing spin we must seek another description for these particles

Introductory RemarksIn this part we will discuss quantum electrodynamics (QED), the theory of photons, and electrons and their interaction. The emphasis here will lie in the practical treatment of physical problems. For formal aspects we will often simply refer to the relevant literature.
